PAPER-BOX MACHINE.

SPECIFICATION forming part of Letters Patent No. 726,955, dated May 5, 19Q3.

Application filed MayZO, 19 02.

To all whom it may concern:

Be it known that I, CHARLES C. LORGION, a citizen of the United States, residing atDetroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Paper-Box Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to machines for the manufacture of paper boxes, and more par-' ticularly to a mechanism by means of which the operator can more readily secure the bottoms -to the sides of the box.

The particular type of box for which the machineis especially designed is one on which the sides arefirst formed and united to produce a tube, and subsequently the bottomis attached thereto by means of a narrow binding-strip of paper or cloth. In the operation of attaching the bottom to the sides as usually performed the sides are first slipped-upon a mandrel. The bottom section is then placed over the end of the mandrel adjacent to the edges of the sides, after which the paper strip, suit-ably coated with paste or glue, is drawn around the edge of the box, so as to overlap both sides and bottom, this latter operation being performed by hand.

It is the object of the present invention to facilitate the work of attaching the bottom to the sides of the box, first, by the peculiar construction and arrangement of the mandrel having a vertical axis of rotation, whereby the work may be more easily held in place while the strip is attached, further, by providing means for thoroughly applying the paste to the strip without interfering with its being freely drawn by the operator, and, still further, by providing means for pasting a plurality of strips which may be simultaneously drawn from the machine and secured to the box.

\Vith these objects in View the invention consists in the construction-as hereinafter described and claimed.

In the drawings, Figure 1 is a longitudinal section through the machine. Fig. 2 is a perspective View thereof, and Fig. 3 is a section Serial No. 108 .257. 2N0 model.)

through the paste-distributing device. Fig. 4 is a detail sectional view of one of the guides.

A is a suitable framework, at one end of which is mounted a shaft B for carrying the rolls of paper strip C. These rolls are held in position upon the shaft bymeans of heads D, adjustably secured to the shaft upon opposite sides of the rolls. The frame A is preferably of general rectangular form and has arranged between the sides thereof a tank E, in. which the paste is placed. Between this paste-tank and the paper-holding shaft B are guides F for the paper strip, preferably in the form of a pair of rolls.

G is an adjustable guide for the strip which is adapted to be inserted below the surface of the paste in the tank E, so as to cause the strip to be fed through the paste.

- H is a wiper over which the paper strip is drawn and adapted to remove the paste from one side of the strip. Upon the'opposite side of the strip from the wiper H is a second wiper I, which is adjustable in relation to the surface of the strip. This latter wiper is adapted to remove the'surplus paste, while permitting a film thereof to remain upon the strip, the amount being varied according to the adj ustment. 1

J is aguide beyond the wipers H and I.

K is a guide arranged in a vertical plane in such relation to the. guide J that the strip passing from the latter to the former is turned from a horizontal into a. vertical plane.

L is a revoluble mandrel. This is preferably attached to a vertical spindle M, which is adjustably secured in relation to the frame A. As shown, the spindle M is vertically adj ustably secured to the arm N, which is attached to a table upon which the frame A is supported. The mandrel L is preferably detachably secured to the spindle, so that it 0 may be exchanged for one of difierent size corresponding to any change in the work. At the lower end of the mandrel is a ledge O, which, as shown, is formed by a plate secured directly to the spindle and .uponwhic'h the mandrel is supported. This ledge serves to support the tube forming the sides of the box, so that at its upper edge it is just slightly is affixed on all sides of the box.

above the top of the mandrel. The spindle M is also vertically adjustable, so that the upper edge of the box thereon will be in line with the'center of a strip drawn from a vertical guide K.

P is a cutter arranged intermediate the guide K and the mandrel L. This, as shown, comprises a stationary shear-blade a anda movable shear b, the latter being provided with an operating-arm c, which is connected by a rod or chain (1 with a foot-lever e.

fis a spring for normally separating the blade I) from the blade at. r I

With the parts constructed as thus far described in operation the tube forming the sides of the box is first placed on the mandrel. The bottom section is then placed within the sides, being supported upon the tube of mandrel, after which the operator draws out a section of the paper strip, pressing its end in contact with the box and simultaneously rotating the mandrel to wind the strip around the box. As this operation proceeds the operator by pressing the thumb or finger on the strip causes it to adhere to the bottom, as well as to the side, and as each corner is passed tucks are formed. Thus when a complete revolution of the mandrel is made the strip Just before the completion of the operation the foot-lever e is pressed so as to operate the shears P and sever the strip, the length of the severed section being preferably sufficient to slightly overlap the end first attached.

The operation above given is greatly facili tated where the mandrel is arranged to 1'0- tate upon a vertical axis. This is for the reason that the operator can more easily hold the bottom of the box in place during the revolution of the mandrel and, further, because the edge of the'strip thus attached to the bottom may be pressed down by the thumb or finger of the operator more readily when the parts are in this position.

In order to properly coat the strip with paste, the guides G must be a certain distance below the surface, and as the level of the paste is changing the guide G is preferably vertically adjustable. As shown, this adjustment is formed by making the guide G in the shape of a bail, having its ends secured in bearings Q at the sides of the frame and its central portion 9 forming the guide for the strip. To vary the depth of the portion 9, the bail may be turned in its bearings to difierent inclinations and may be held in any position of adjustment by set-screws h.

The wipers H and I are preferably formed as shown in Figs. 1 and-2, in which the wiper I is formed by a shaft journaled in bearings R on opposite sides of the machine. The wiper H is formed by a rod secured to the shaft I and spaced therefrom. At one end of the shaft I is a handle S, by means of which the shaft may be rotated, and to hold it in any position of adjustment set-screws i are arranged in the bearings R. With the construction described the paper strip is passed between the rod H and shaft I, and the latter is then adjusted inaposition where the strip in passing from the rod H to the guide J will just slightly clear the shaft I. Thus when the strip is drawn the paste deposited on both sides thereof while beneath the surface will be carried up until the wiper H is reached. Here the pasteon the lower side of the strip will be entirely removed by said wiper, while the paste on the upper side of the strip will be restricted to a film equal in thickness to the space between the strip and the shaft I. It will be understood that whenever the shaft constituting the wiper I is rotatively adjusted the distance between the strip and said shaft is varied, so that any desired amount of paste may be allowed to remain upon the strip.

The advantage of first passing the strip through the paste, so as to coat both sides thereof, and then removing the paste from one side is that the latter surface, even after the paste is entirely scraped off, remains in a soft and slippery condition. This facilitates the WOlkOf the operator in pressing down the strip, for the reason that the surface being soft and lubricated is not as severe upon the thumb of the operator as a dry surface would be. It will be understood that where the operationofpressing down the strip is repeated for many-hours during the day any harshness in the strip is likely to result in an abrasion of the skin of the finger, which renders further work for the time difficult or impossible. Experience hasdemonstrated that-a paste-moistened surface produces little injury even after many hours work. Another advantage of coatingv both sides of the strip is that it is thereby rendered more pliable,whioh facilitates the work of attaching it. a For certain classes of work it is desirable to employ more than one thickness of strip. As shown in Fig. 2, a plurality of strips may be simultaneously passed throughthe machine, their respective rolls beingplaced side by side upon the frame A. The strips may then be passed adjacent to each other through the guides F, beneath the guide G, and between the wipers H and I to the guide J From this point they are passed to two sepa- ICC rate vertical guides T, which may be similar in construction to the vertical guide K, and thence to said guide K, where they are brought in contact with each other. In passing to the guides T both strips are turned in the same direction, andsaid .guide is so positioned relative to the guide K that that surface of each strip from whichthe paste has been removed will bear against the guides. The guide K is also preferably laterally adjustable transversely of the machine, so that it may be positioned to cause the strip to bear thereagainst with the surface from which the paste has been removed, said adjustment being effected through the medium of screws 70,

working in slots is. With this arrangement of parts the operation is performed in the same manner as the one previously described, with the exception that the operator draws both of the strips simultaneously and causes them to adhere to each other when drawn past the guide K. They may then be Wound around the box and pressed down in the manner before described.

While I have shown the mandrel L as rotating upon a vertical axis, it is evident that it is not necessary that this axis should be in an absolutely vertical plane. It is only essential that the mandrel should be held in a substantially upright position, so that the bottom of the boxes will remain in position after once being placed in relation to the sides of the box.

hat I claim asmy invention is- 1. In a paper-box machine the combination with the supporting-frame, of a paste-receptacle located below the upper surface of said frame and supported thereby, means for guiding a binding-strip through said receptacle, a guide on the upper surface of the supporting-frame for causing the bindingstrip to assume a vertical position after leaving the paste-receptacle and traverse above said surface, a revoluble mandrel adjacent to said last-mentioned guide, a vertical spindle by which said mandrel is carried, and means for adjusting said spindle whereby the upperv end of the work supported upon the mandrel may be projected above the upper surface of the supporting-frame.
